Abstract

Improvements in the methods of manufacturing cellular isolations characterized by a method that comprises the extrusion operations of a plastic material, which contains a blowing agent, on a conductor at a temperature lower than that in which the blowing agent is released from its gas and the heating of the conductor by the passage of current through it, which causes the blowing agent next to the conductor to detach from the gas, causing the immediate insulation to the conductor to take on the cellular form, which is surrounded by a solid insulation layer.
